Title: Improvements relating to electric switches or relays and to timing devices therefor
IPC: H01H50/88
Filed: 1930-06-26
Abstract: 364,079. Electromagnetic switches ; controllers. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London.-(Assignees of Wensley, R. J. ; 111, Maple Avenue, Edgewood, Pennsylvania, U.S.A.) June 26, 1930, No. 19511. Convention date, June 27, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 38 (iii) and 38 (v).] Actuating electromagnetically.-A n electric switch, contactor, or relay has the movement of its movable contact member held up intermittently in closing by an armature which is attracted to an intermittently energized electromagnet so that the movement of the switch contact member takes place in steps. As shown in Figs. 1 and 2 the contactor 14 in closing extends a spring 15 which biases the pivoted contact member 12 towards its closing position. The contact-member 12, however, carries an armature 13 which is adjacent to a gap 4 in the magnetic circuit of a coil 1. The coil 1 is in series with interrupter contacts 8, 9 operated by an armature 7 carried by a trembler blade 6 so that the armature 7, which is mounted near a second air gap 5 in the magnetic circuit of the coil 1, causes a succession of makes and breaks in the circuit of the coil 1 and consequently causes the alternate attraction and release of the armature 13 on the arm 12. The intermittent attraction of the arm 12 permits this arm to advance in steps to close the contacts, 18, 19, thus acting as a time delay in the contact closure, the value of which is dependent on the characteristics of the interrupter. If relays of the type described are employed in motor control systems the closing of contacts. 18, 19 may cause the energization of the succeeding contactor. In a modification, Fig. 3 (not shown), the time-delayed relay contact arm may be arranged so as to move longitudinally.

Abstract: 1,196,689. Optical navigation. MARCONI CO. Ltd. 27 Feb., 1969 [25 April 1968], No. 19681/68. Addition to 1,123,950. 1,1g Heading H4D. [Also in Division G1] Two components of a vehicles velocity over a surface of variable reflectivity are respectively detected by pairs of photo detectors A, B and C, D, each component being determined by feeding the detectors outputs to a correlatorone via a variable delay-and thereby determining the time taken for an area of surface to pass from the field of view of one detector to the other. The vehicle is exemplified as a car and means are provided illuminating the areas under each detector, said areas being such (e.g. as shown in dotted lines for detectors A and B) that at least part of the ground illuminating under a first detection of a pair will pass to be illuminated under the second detection of said pair. The components may be orthogonal as shown and signals proportional thereto are fed to a rolling ball moving map display Fig. 4. One component signal causes rotation of motor 8 and, by means of shaft gear 6 engaging teeth 5 on the inside of ring 1, the rotation of ring 1 bearing against the ball bearing 18. The ring rotates on axle 2 journalled in bearings 4 in a ring 3. Ring 3 is rotated in accordance with the second component of velocity by means of motor 17 and shaft gear 15 engaging ring teeth 14. Ball 18 is thus caused to rotate in a direction such that a map 19, frictionally supported by said ball, moves in accordance with the vehicles velocity, a pair of cross wires 21/22 indicating the position of the vehicle.

Patent GB-743229-A (GB)
Title: Improvements in or relating to the manufacture of regenerated cellulose films
Inventor: BERRY WILLIAM
IPC: C08J7/06
Filed: 1953-07-16
Abstract: In order to prevent films of regenerated cellulose from sticking together there is applied in aqueous suspension or emulsion a very thin layer of a water-soluble soap and a waterinsoluble soap, in the absence of waxes or resins.  The water-soluble soap is preferably sodium palmitate and the water-insoluble soap is preferably calcium palmitate, the proportions of the two soaps being between 1 : 1 and 5 : 1 and the total soap content not exceeding 2 per cent by weight of the oven-dry film.  Other suitable soaps are metallic or ammonium salts of fatty acids comprising at least 10 carbon atoms in the molecule.  Fatty acids include both saturated and unsaturated monobasic aliphatic carboxylic acids, e.g. stearic, palmitic, lauric, oleic and ricinoleic acids.  Watersoluble soaps include the sodium, potassium and ammonium salts, water-insoluble soaps include the calcium, magnesium and aluminium salts.  The regenerated cellulose film may be unsoftened, but it is preferred to treat film which contains up to 25 per cent of softening agent such as glycerol, but any water-soluble softening agent may be used, e.g. diethylene glycol, triethylene glycol, urea or mixtures thereof.  A convenient way of forming the two kinds of soap on the film is to treat the gel film with a solution of a salt of a metal capable of yielding a waterinsoluble soap so that some of the metal ions are adsorbed, then treating the film with a solution of a water-soluble soap and a softener, whereby some of such soap is absorbed and some reacts with the adsorbed metal ions to form a waterinsoluble soap.  The bath of water-soluble soap may also contain a water-soluble non-ionic surface-active agent such as polyethylene glycol tertiary dodecyl thioether, or a water-soluble anionic surface-active agent such as the sodium salt of dodecyl naphthalene sulphonic acid, in a proportion of approximately 0.1 per cent by weight of the bath.  In an example, a regenerated cellulose film from viscose is thoroughly washed and passed through a bath of hard water containing 50 parts per million of calcium as water-soluble calcium salts at 15 DEG  C. for 30 seconds.  Excess solution is squeezed out and the film washed with very soft water in countercurrent flow, to remove the calcium salts.  The film then passes into a bath of soft water containing 0.25 per cent sodium palmitate, 5 per cent glycerol and 0.1 per cent polyethylene glycol tertiary dodecyl thioether at 60 DEG  C. for 5 seconds.  Excess solution is removed by squeezing and the film dried between drying rollers heated to 80 DEG  C. to give a film containing 7 per cent water, 14 per cent glycerol, 0.3 per cent calcium palmitate and 1 per cent sodium palmitate and having increased slipperiness and little tendency to stick to adjacent film. Specifications 386,775 and 472,264 are referred to.
